after i got the new ecu installd the red lightt for the oil stays on and the water temp is the same.... how do i fix this problem... the std ecu is still controlling the auto ect but the neww ecu is controlling engine... an its an EL

run a 2nd water temp senser into thermostat housing and use one for std ecu and other for aftermarket comp, and the oil pressure should work as per standard unless for some reason they used it in ur aftermarket computer, wat aftermarket comp u runnin, the cheaper ones like stingers, microtech and haltech wont have anything to do with ur pressure sender, just check the wiring is connected to it
